Smart water purification systems utilize advanced multi-stage filtration technology to effectively remove impurities, heavy metals, bacteria, viruses, and other harmful substances from water, while retaining minerals and trace elements that are beneficial to the human body.

[0003] The currently used smart water purification systems are prone to various faults during daily use due to the complex composition of the purified water. Due to the lack of data monitoring and analysis of various parameters during the operation period of the water purification system, it is impossible to respond to various faults in the water purification system in a timely manner, resulting in a decline in the user experience of the smart water purification system.

[0006] The filter status analysis module is used to perform comprehensive calculation and analysis on the water purification status parameters of the water purification system in each operating period, and obtain the water purification filter status parameters of the water purification system in each operating period. The specific calculation and analysis method is as follows:

[0007] The water purification state parameters of the water purification system corresponding to each operating period are obtained from the water purification state parameters of the water purification system corresponding to each operating period, and the water inlet pressure, outlet pressure, inlet flow rate and outlet flow rate of the water purification system corresponding to each operating period are obtained, which are recorded as IP i OP i , IQ i and OQ i, where \(i\) represents the number of each operation period, \(i = 1, 2, \cdots, n\), and \(n\) represents the total number of the numbers of each operation period. Calculate the difference between the inlet pressure and the outlet pressure of the water purification system corresponding to each operation period to obtain the inlet pressure difference of the water purification system corresponding to each operation period, denoted as \(\Delta XP\). i , calculate the difference between the inlet flow rate and the outlet flow rate of the water purification system corresponding to each operation period to obtain the inlet flow rate difference of the water purification system corresponding to each operation period, denoted as \(\Delta XQ\). i ;

[0008] Substitute the above data into the calculation formula to calculate the pressure-flow state coefficient \(S\) of the water purification system corresponding to each operation period. 1i , where \(\alpha\) represents a set weight factor, \(0 \lt \alpha \lt 1\), which is used to adjust the proportion of the pressure difference and the flow rate difference of the water body in the pressure-flow state coefficient.

[0009] Obtain the filter element usage duration data of the water purification system corresponding to each operation period from the database, denoted as \(LT\). i , and at the same time obtain the set standard usage duration of the filter element, denoted as \(LT0\); among them, the filter element usage duration is transmitted to the database for storage in real time.

[0010] Substitute the above data into the calculation formula to calculate the filter element state coefficient \(S\) of the water purification system corresponding to each operation period. 2i ;

[0011] The water body purification state parameters of the water purification system corresponding to each operation period are jointly composed of the pressure-flow state coefficient and the filter element state coefficient of the water purification system corresponding to each operation period.

[0012] The physical property analysis module is used to comprehensively calculate and analyze the water body physical parameters of the water purification system corresponding to each operation period to obtain the water body physical purification state coefficient of the water purification system corresponding to each operation period.

[0013] The chemical property analysis module is used to comprehensively calculate and analyze the water body chemical parameters of the water purification system corresponding to each operation period to obtain the water body chemical purification state coefficient of the water purification system corresponding to each operation period.

[0014] The fault warning and evaluation module is used to evaluate and analyze the water body purification state parameters, the water body physical purification state coefficient, and the water body chemical purification state coefficient of the water purification system corresponding to each operation period, and generate a fault warning signal for the water purification system corresponding to each operation period.

[0019] The water purification state parameters of water bodies during each operation period of the water purification system are jointly composed of the inlet water pressure, outlet water pressure, inlet water flow rate, and outlet water flow rate corresponding to each operation period of the water purification system.

[0020] Furthermore, a comprehensive calculation and analysis is performed on the physical parameters of water bodies during each operation period of the water purification system, and the specific calculation and analysis method is as follows:

[0021] Extract the inlet water temperature, outlet water temperature, inlet water turbidity, outlet water turbidity, inlet water conductivity, and outlet water conductivity corresponding to each operation period of the water purification system from the physical parameters of water bodies during each operation period of the water purification system, and denote them as IW i , OW i , IZ i , OZ i , ID i , and OD i ;

[0023] According to the formula WS i = w1 * ΔSW i + w2 * RZ i + w3 * RD i calculate the water physical purification state coefficient corresponding to each operation period of the water purification system, where w1, w2, and w3 all represent set weight factors, and w1 + w2 + w3 = 1.

[0024] Furthermore, comprehensive calculation and analysis are performed on the water body chemical parameters of the water purification system corresponding to each operation period. The specific calculation and analysis method is as follows:

[0025] Extract the inlet pH value, outlet pH value, inlet total organic carbon, outlet total organic carbon, inlet hardness value, and outlet hardness value of the water purification system corresponding to each operation period from the water body chemical parameters of the water purification system corresponding to each operation period. At the same time, obtain the pH standard value, total organic carbon standard value, and hardness standard value of the water purification system corresponding to each operation period from the database. Compare the difference between the pH standard value and the minimum pH value of the water purification system corresponding to each operation period with the difference between the maximum pH value and the minimum pH value to obtain the standardized pH value. Similarly, calculate the standardized total organic carbon and hardness values of the water purification system corresponding to each operation period. Multiply the standardized pH value, total organic carbon, and hardness values of the water purification system corresponding to each operation period by the corresponding set weight factors and sum them to obtain the water body chemical purification state coefficient of the water purification system corresponding to each operation period.

[0026] Furthermore, evaluation and analysis are performed on the water body purification state parameters, water body physical purification state coefficient, and water body chemical purification state coefficient of the water purification system corresponding to each operation period. The specific evaluation and analysis method is as follows:

[0027] Obtain the preset pressure-flow state coefficient threshold and filter element state coefficient threshold of the water purification system corresponding to each operation period from the database, denoted as SY 1i and SY 2i respectively. Taking the preset pressure-flow state coefficient threshold of the water purification system corresponding to each operation period as the radius value and the preset filter element state coefficient threshold of the water purification system corresponding to each operation period as the height value, draw a cylinder, and denote this cylinder as the water body purification state parameter threshold graph; specifically, the preset pressure-flow state coefficient threshold and filter element state coefficient threshold of the water purification system corresponding to each operation period are both artificially preset values through a large amount of historical data and experimental data.

[0028] At the same center position, taking the pressure-flow state coefficient of the water system corresponding to each operation period as the radius value and the filter element state coefficient of the water purification system corresponding to each operation period as the height value, draw another cylinder, and denote this cylinder as the water body purification state parameter graph;

[0029] If the volume of the water body purification state parameter graph is greater than the water body purification state parameter threshold graph, and the height of the water body purification state parameter graph is greater than the water body purification state parameter threshold graph, it indicates that the working state of the filter element of the water purification system is abnormal, and a filter element failure signal is generated;

[0030] If the volume of the water purification status parameter graph is greater than that of the water purification status parameter threshold graph, and the radius of the water purification status parameter graph is greater than that of the water purification status parameter threshold graph, it indicates that the water purification status of the water purification system is abnormal, and a water purification abnormal signal is generated;

[0031] If the volume of the water purification status parameter graph is greater than that of the water purification status parameter threshold graph, and both the height and radius of the water purification status parameter graph are greater than those of the water purification status parameter threshold graph, it indicates that the water purification status of the water purification system is abnormal and the filter element working status is abnormal, and a water purification abnormal signal and a filter element failure signal are generated;

[0033] Further, obtain the preset water physical purification status coefficient thresholds corresponding to each operation period of the water purification system from the database, compare the water physical purification status coefficients corresponding to each operation period of the water purification system with the preset water physical purification status coefficient thresholds. If the water physical purification status coefficient corresponding to a certain operation period of the water purification system is greater than the preset water physical purification status coefficient threshold, it indicates that the water physical purification status of the water purification system corresponding to this operation period is poor, and a physical purification warning signal is generated. Otherwise, it indicates that the water physical purification status of the water purification system corresponding to this operation period is good, and no physical purification warning signal is generated;

[0034] Obtain the preset water chemical purification status coefficient thresholds corresponding to each operation period of the water purification system from the database, compare the water chemical purification status coefficients corresponding to each operation period of the water purification system with the preset water chemical purification status coefficient thresholds. If the water chemical purification status coefficient corresponding to a certain operation period of the water purification system is greater than the preset water chemical purification status coefficient threshold, it indicates that the water chemical purification status of the water purification system corresponding to this operation period is poor, and a chemical purification warning signal is generated. Otherwise, it indicates that the water chemical purification status of the water purification system corresponding to this operation period is good, and no chemical purification warning signal is generated;

[0035] The fault warning signals corresponding to each operation period of the water purification system are jointly composed of the water purification abnormal signal, the filter element failure signal, the physical purification warning signal, and the chemical purification warning signal corresponding to each operation period of the water purification system.
